Not sure if it's the right place to post,
Trying to get the browser logs this way:

browser.manage().logs().get('browser').then(function(browserLog) { ... }));

but i get an error:

WebDriverError: POST /session/36718c58-6808-4ba0-9600-3d33fffc0d30/log did not match a known command

NB: works with Chrome.
